These beauties are made with love and industrial strength adhesives and surgical steel findings.
To clean the shiny acrylic, just wipe down with a baby wipe or gentle cleaner (i.e. dish soap or surface cleaner) and water. Then use dry cloth to remove any streak marks.
These are made from a range of fabrics that are cotton and polyester blend. They are washed best in a cold wash and ironed with a low temperature iron with a cotton overlay to be safe.
